Truth is really important sometimes, but so far I've been bad about identifying when.

I know a fair bit about cognitive biases and ideal probabilistic reasoning, and I'm pretty good at applying it to scientific papers that I read or that people link through Facebook. But these applications are usually not important.

But, when it comes to my schoolwork and personal relationships, I commit the planning fallacy routinely, and make bad predictions against base rates. And I spend no time analyzing these kinds of mistakes or applying what I know about biases and probability theory.

If I really operationalized my belief that only some truths are important, I'd prioritize truths and apply my rationality knowledge to the top priorities. That would be awesome.
